HENRY HAMPER, DETROIT, MICHIGAN.

TOBACCO-PIPE.

To all whom it my comm:

Be it known that I, HENRY HAMPER, a

citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented'a certain new and useful Improvement in Tobacco-Pipes, and declare the following to be a full, clear, and exact description of the same, such aswill .enable others skilled in the art to which it pertains to make and use the same, reference being had .to the accompanying drawings, which form a part of this specification.

My invention relates to an improvement in tobacco pipes, shown in the accompanying drawings and ,more particularly described 'in the following specification and claim.-

One of the objects of my invention is to regulate the drafts through the pipe that the disagreeable biting sensation produced by the smoke upon the tongue will be eliminated.-

I tion through the pipe.

- Another object is to prevent the collection into and through the stem endangering clogging of the passage through the latter.

Other advantages and improvements will hereafter appear. 1 In the drawings accompanying this specification F igure 1 is a perspective view of the pipe showing the damper controlling the auxiliary draft passage. Fig. 2 is a perspective view of the stem disconnected from the pipe bowl. Fig. '3 is a longitudinal secperspective view of one of the parts of a modification of the device. Fig. 5 is a perspective view of theco-acting part. Fig. 6 is a cross-section of the assembled parts shown in Figs. 4 and 5, installed in the wall of a pipe.

' Referring now to the letters of reference placed upon the drawings :A denotes the bowl of the pipe and A that portion ofthe stem integral therewith.

Bis a mouth-piece having screw-threaded connection with the tubular portion B sleeved'within the 'stem A of the pipe bowl. The forward end of the tubular portion B,

adapted to register with a series of corresponding ports through the Wall of the pipe communicating with its chambered portion.

C is a pro ecting ear or lug; formed. on

the face of the disk C, by which means the opening C through the disk may be adjusted with respect to the ports a in the wall of the pipe, that the volume of draft through the latter may be brought under control.

In the modification shown in Figs. 4, 5 and 6, the perforated disk-shaped damper C is pivoted in a cup-shaped portion D pro vided with co-acting perforations (Z, adapted to register with those of the disk. The Walls 03 of the portion D are given a tapering formation in order that they may be tightly wedged in the opening provided in the wall of the pipe for its reception.

Having indicated the several parts by reference letters, the construction and operation of the pipe will be, readily understood.

Assuming that the pipe bowl has been properly filled and the tobacco lighted, the volume of air admitted through the bottom of the bowl is regulated by adjusting the disk-shaped damper C to provide a draft of suflicient proportion to insure the tobacco and bowl being kept dry and free from moisture or condensation. It will also be found that the admission of air below the burning plane of the tobacco, has the effect of eliminating entirely, or at least to a great extent, the disagreeable burning or biting sensation experienced by all who smoke the type of pipe commonly used. I have alsofound that by this arrangement of drafts the bowl of the pipe is kept in a cooler condition and does not char, as in ordinary constructions.

The closed end of the removable stem portion, which I prefer to project well within the bowl *of the pipe, isformed of meera schaum or other heat resisting material, and is provided with a series of relatively small apertures to screen the passage through the stem against the entry of tobacco or ash, thereby keeping it open that the smoke may freely pass through itto the mouth of the smoker. By forming the tubular portion B with a relatively large bore and making the same separable from the mouth piece, the parts may be easily cleaned.

In the modification shown in Figs. 4c, 5 and 6, the portion D may be removed by forcing it outwith the fingers from the inside of the bowl, the pipe may then be cleaned through the opening thereby provided.

Having thus described my invention, what I claim is':

In a tobacco pipe, a bowl provided with a plurality of auxiliary draft openings, a rotary disk-shaped damper flush with the wall of the pipe having a series of openings adapted to register with the auxiliary draft 7 openings, said bowl provided with an integral projecting neck having an enlarged bore opening into the pipe bowl, a removable tubular portion supported in said neck of portion provided with apertures connecting 25 the bowl with the tubular portion, and a mouth piece secured to the other end of the tubular portion, substantially as described.

In testimony whereof, I sign this specification in the presence of two witnesses.
